Well, I've recently seen them used in MSDN archive URLs :-) and I
believe Apple plists use them to tag nodes.

Uh, if I were young, slim, and sexy I really wouldn't want my stalkers
to know when I plan to walk alone in Central Park, or when I'm going
anywhere for that matter.  And I would certainly give that concern
priority over them knowing whether I made a particular appointment via
my iPhone or Barrack Obama's PC.  Oops, you're not supposed to know I
have access to that, I guess it would be scary if that leaked.  Yeah,

No, they shouldn't include that information if it can easily be
avoided.  But get real.  When Emacs net apps all route via TOR only by
default, then I'll concede you have a point.
